Bahz said in his narration: Habib ibn Abi Thabit narrated to me, he said: I heard Abu al-Minhal, a man from Banu Kinanah, say: I asked al-Bara' about currency exchange (al-sarf). He said: Ask Zayd ibn Arqam, for he is better than me and more knowledgeable. He said: I asked Zayd, and he mentioned the hadith.
